机翼/外挂颤振主动抑制的控制律研究

INVESTIGATION OF CONTROL LAWS FOR THE SUPPRESSION OF WING/STORE FLUTTER

  • 摘要: 本文介绍了对机翼/外挂系统的颤振抑制控制律的研究。并用三种控制律的结果进行了风洞实验验证。结果表明:控制律的设计是成功的,理论计算与实验结果吻合良好。 文中重点介绍了两种控制律,它们都是以现代控制理论为基础。首先,把最优控制理论与颤振分析的状态空间法相结合,得到状态反馈。然后导出不同的输出反馈。文中,还讨论了该系统的阵风减缓和稳定裕度。 为对比起见,还给出了在同一模型上,用气动能量概念方法导出的控制律。由此,可看出它们在颤振抑制效益上的差异。

     

    Abstract: Control laws for the suppression of wing/store flutter are investigated in this paper. The wing tunnel test was conducted for three control laws used. It shows that the design of control laws is successful and an excellent agreement between the calculated and test results is achieved.Two kinds of flutter suppression control laws based on modern control theory are presented emphatically. State feedback are obtained by the combination of optimal control theory and state-space method used in flutter analysis, ...
